Abstract

A turbine, including a rotor on a shaft, and having in combination stationary nozzles discharging steam at a first pressure or pressures thereby producing impulse forces on the rotor; internal passages in the rotor producing a pressure head increase in the discharged steam, while simultaneously accelerating the steam, the steam discharged to a second pressure lower than the first pressure, producing reaction forces on the rotor; seal means between the stationary nozzles and the rotor, maintaining the pressure difference between the first pressure and the second pressure while minimizing steam leakage past the internal passages, turbine operations producing shaft power.

Claims (14)

1. A turbine, including a rotor on a shaft having an axis, and having in combination:

a) stationary nozzles discharging steam at a first pressure or pressures thereby producing impulse forces on said rotor, b) the rotor having blades forming internal passages producing a pressure head increase in the discharged steam, while simultaneously accelerating the steam, the steam discharged to a second pressure lower than the first pressure, producing reaction forces on the rotor, c) seal means between the stationary nozzles and the rotor, maintaining the pressure difference between the first pressure and the second pressure while minimizing steam leakage past the internal passages, said seal means carried by the rotor and oriented in a radial, direction relative to said axis to seal against non-rotating nozzle surface or surfaces to restrict steam flow that would otherwise bypass said passages formed by the rotor blades, d) turbine operation producing shaft power, e) and including passages in the rotor between the blades configured to centrifuge liquid and/or solid particles in the steam directionally away from passage inlets, f) each said rotor blade, in cross section, having surfaces configured to define converging passages between said rotor blades causing an increase in fluid pressure above said first pressure such that flow pressure in the passages increases to a maximum value greater than said first pressure and then decreases to a pressure less than said first pressure.
2. The combination of claim 1 wherein the rotor consists essentially of titanium alloy for erosion resistance.
3. The combination of claim 2 wherein certain of said seal means are provided at the same diametric location on opposite sides of the rotor to produce a force balance on the rotor.
4. The combination of claim 1 wherein holes are provided at locations radially inward from said passages, to enable steam from one side of the rotor to translate to the other side of the rotor, to produce a balance force on the rotor.
5. The combination of, claim 1 where passages are provided radially outwardly of the rotor to enable steam flow from one side to the other side of the rotor to produce a force balance on the rotor.
6. The combination of claim 1 having a shaft seal characterized in that pressurized gas provides a means to prevent leakage of steam to the surroundings and wherein non-contact structural faces providing centrifugal forces are used to reduce pressurized gas leakage into the steam.
7. The combination of 1 in which additional rows of stationary nozzles, rotor passages and seal means are provided on the same rotor and oriented in radially outward directions to enable additional power producing steam expansions.
8. The combination of claim 1 wherein the turbine shaft drives gearing which drives an electric generator at synchronous speed to produce electric power from the steam energy.
9. The combination of claim 1 wherein the turbine shaft directly drives a high speed electric generator at a speed above synchronous speed producing electric power from the steam energy.
10. The combination of claim 1 wherein the turbine shaft drives a pump.
11. The combination of claim 1 wherein the turbine shaft drives a compressor.
12. The combination of claim 8 wherein control means and electrical means are provided to produce a complete, automated and self-regulated system to produce electric power from steam energy and to enable ease of installation.
13. The combination of Claim 8 wherein the rotor shaft, gearing shaft and generator shaft are vertically oriented to enable a compact assembly.
14. The combination of claim 1 wherein control means and electrical means are provided to produce a complete, automated and self-regulated system to produce electric power from steam energy and to enable ease of installation.
